Monostrand duct



FIG. 1 is an upper perspective view of the monostrand duct showing my design.

FIG. 2 is a side view thereof, wherein an opposite side view is a mirror image thereof;

FIG. 3 is top plan view thereof, wherein a bottom view is a mirror image thereof;

FIG. 4 is an end view thereof; and,

FIG. 5 is a side elevation view thereof, showing a cable extending therethrough.
